Approximate square root of 83 to to the nearest integer.

Leon evaluated the expression (–4a – 6) + a2 for a = 8. (-4(8) - 6) + 82 (-32-6) + 82 (-38) + 82 (-38) + 16 –19 + 16 –3 Analyze

zhuklara [117]

Answer:

Option 3 is correct as Leon multiplied 8 by 2 when he should have raised 8 to a power of 2.

Step-by-step explanation:

Given : Leon evaluated the expression $(-4a-6)+a^2$ for a=8

(-4(8) - 6) + 82 , (-32-6) + 82 , (-38) + 82 , (-38) + 16 –19 + 16 –3

Leon's work is not so proper , Option 3 is correct as Leon multiplied 8 by 2 when he should have raised 8 to a power of 2.

Correct steps are :

Step 1 : $(-4a-6)+a^2$

Step 2 : Put a=8 in the equation we get,

$=(-4(8)-6)+8^2$

$=(-32-6)+8^2$

$=-38+8^2$

$=-38+64$

$=26$

Therefore, correct answer is 26.

Whats the next two terms in order are p+q, p , p-q

Law Incorporation [45]

Answer:

p - 2q and p - 3q

Step-by-step explanation:

A Series is given to us and we need to find the next two terms of the series . The given series to us is ,

$\rm\implies Series = p+q , p , p - q$

Note that when we subtract the consecutive terms we get the common difference as "-q" .

$\rm\implies Common\ Difference = p - (p + q )= p - p - q =\boxed{\rm q}$

Therefore the series is Arithmetic Series .

Arithmetic Series:- The series in which a common number is added to obtain the next term of series .

And here the Common difference is -q .

Fourth term :-

$\rm\implies 4th \ term = p - q - q = \boxed{\blue{\rm p - 2q}}$

Fifth term :-

$\rm\implies 4th \ term = p - 2q - q = \boxed{\blue{\rm p - 3q}}$

Therefore the next two terms are ( p - 2q) and ( p - 3q ) .

Determine whether the equation represents direct, inverse, joint, or combined variation.

Dominik [7]

Answer: The retort to the peculiar proposed interrogate is definitively identified as ‘Joint Variation’, interchangeably acknowledged as ‘Combined Variation’.

Step-by-Step Explanation:

Given the mathematical statement,
Y = 4x^3z^3

Such coherently demonstrates the principle of a foreign variable, ‘y’, which whom varies directly as the product of at least two distinct or distinguishable quantities occur.

The mentioned is the precise definition of Joint Variation, where ‘y’ is jointly proportional to the product of the minimum agglomerate of two quantities, whilst a presence of a nonzero constant, k.
